CAPE TOWN - It's not yet clear when the state will wrap up its case against Shrien Dewani, who is accused of orchestrating his wife, Anni Hindocha Dewani's murder.

The prosecution has called 16 witnesses so far.

The British businessman stands accused of hiring hit men to kill Anni in Cape Town while the two were on their honeymoon in November 2010.

The possibility remains that the defence may bring an application to acquit Dewani when the state closes its case.

It's unclear at this stage how many witnesses the state still intends calling.

On Friday a forensic analyst took the stand.

She was called to explain why gunshot residue was found on a glove belonging to a man who denies shooting Anni.

Colonel Thandiwe Mlabateki said primer residue analysis can't determine exactly who fired a shot because particles could land on anything within a two metre radius.
